BACKGROUND:
The objective of the present study was to evaluate the varying efficacy of general anesthesia (GA), combined spinal-epidural anesthesia (CSEA), and total intravenous anesthesia (TIVA) on the occurrence of deep vein thrombosis (DVT) following total knee arthroplasty (TKA).MATERIAL AND METHODS:
From July 2013 to May 2015, a total of 197 cases of patients who had undergone TKA treatment at either the Drum Tower Hospital or Nanjing General Hospital of Nanjing Military Command were recruited to participate in the study. The patients in the study were separated into 3 groups depending on the anesthesia approach received: the GA group, the CSEA group, and the TIVA group. The baseline characteristics and relative parameters of patients were monitored before and after surgery for analytic purposes. A 3-month follow-up after surgery was conducted to observe the rate of DVT occurrence and any DVT-related complications.RESULTS:
The TIVA group exhibited significant decreases in relation to the swallowing time reflex, extubation, and consciousness recovery in comparison to other groups in the study. Additionally, platelet count was significantly decreased and there was drastic extension of the activated partial thromboplastin time (APTT) in the CSEA group and the TIVA group. There were clear differences in the incidence of DVT and its complications among the 3 groups. The TIVA group displayed the lowest incidences of DVT and DVT-related complication during the study. Based on logistic regression analysis, the type of anesthesia was utilized as an independent correlative factor for the occurrence of DVT after surgery.CONCLUSIONS:
The results obtained during the study established a clinical basis for comparative analysis of various anesthesia methods. We found that, compared with GA and CSEA, patients undergoing TIVA had a reduced rate of risk in relation to the occurrence of DVT following TKA.
